Valais is Switzerland's alpine heartland — home to Zermatt, Verbier, and the Matterhorn. Companies in tourism, hydroelectric energy, and wine production establish Sion-based legal entities for this unique alpine market. This guide covers everything you need to know about establishing a legal entity in Valais (VS) — from choosing the right company type to post-registration compliance requirements.
"Valais companies are almost always in tourism, real estate, energy, or wine. The geography dictates the economy. The higher tax rate is accepted because the business cases are geographically anchored — you cannot move a ski resort to Zug. We've incorporated many alpine resort operators, helicopter services, and luxury property developers in Valais. Markus Pritzker, SwissFirma"
Why businesses establish in Valais for tourism and alpine industries
The Rhône Valley and its dramatic alpine tributaries define Canton Valais economically. Switzerland's highest peaks — including the Matterhorn (4,478m) — and most famous ski resorts — Zermatt, Verbier, Crans-Montana, Saas-Fee — are in Valais. The canton generates over 30% of Switzerland's hydroelectric power and produces exceptional wines (Fendant, Dôle) on its sun-facing valley slopes. For companies whose business is the alpine environment, Valais is the only logical choice.

Corporate tax rates in Valais (VS)
Effective combined corporate tax rate: 18.84%
Breakdown: 7.83% federal + 6.80% cantonal + 4.21% municipal (Sion city)
Valais's combined rate of 18.84% (Sion city) is among the higher Swiss cantonal rates. The breakdown: 7.83% federal, 6.80% cantonal, 4.21% municipal. As a predominantly tourism and natural resource canton, Valais's economic rationale for registration rarely depends on tax optimisation — businesses are there because of their physical connection to the land or resort. TRAF 2020 reforms introduced an IP Box and R&D deductions, but these are less commonly used in Valais than in tech-focused cantons.
Minimum share capital requirements
- GmbH (Société à responsabilité limitée / SàGL): CHF 20,000 — fully paid up at registration
- AG (Société anonyme / SA): CHF 100,000 — at least 50% paid up at registration
